摘要：
A device and method for generating a representation of a subject's attention level. The device comprises means for measuring brain signals from the subject； means for extracting temporal features from the brain signals； means for classifying the extracted temporal features using a classifier to give a score x1； means for extracting spectral-spatial features from the brain signals； means for selecting spectral-spatial features containing discriminative information between concentration and non-concentration states from the set of extracted spectral-spatial features； means for classifying the selected spectral-spatial features using a classifier to give a score x2； means for combining the scores x1 and x2 to give a single score； and means for presenting said score to the subject.
